Abstract
Bis(4-methoxybenzoyl), bis(4-chlorobenzoyl), and dibenzoyl peroxide were photolyzed in various solvents by 308-nm laser pulses to determine the rate constants for decarboxylation of the corresponding benzoyloxyl radicals. The activation energies of this process were lower than those estimated by indirect methods.Keywords
